COVER LETTER: This is the schedule for the 3.6cm NME and ftp fringe-test on 20 October, 2023. involving the following antennas: Wb, Ef, Mc, On60, T6, Ur, Tr, Hh, Ir, Wz; with Ud & Ms in the first 3 scans. The NME uses a standard setup with 4096 Mbps. The schedule consists of long integrations on calibrators 0003-066, 0202+319 for FTP fringe tests. We will use 0204+316 for phase referencing. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 18:08:00 (scan 1, 2 sec, 0202+319) 18:30:00 (scan 3, 2 sec, 0202+319) 19:00:00 (scan 5, 2 sec, 0202+319) 19:30:00 (scan 9, 2 sec, 0202+319) 20:00:00 (scan 13, 2 sec, 0202+319) 20:30:00 (scan 17, 2 sec, 0202+319) Good luck with the session!
